The emergence from a home cage in rats (Rattus norvegicus) was investigated as a function of strain and sex. Both sexes from the Donryu/Hos, Long-Evans, Sprague-Dawley/Crj (CD), Wistar/Crj, Wistar-Imamichi/Iar, F344/DuCrj, and the Tsukuba High-and Low-Emotional strains (THE and TLE) were employed as subjects. It was found that the Long-Evans and THE were the two extremes. That is, all the Long-Evans rats emerged from the home cage, whereas none of the THE did. Females emerged more frequently than males. These results were discussed in terms of emotionality and activity.
